上海凱研機械設備有限公司提供閥鎖，閥門聯(lián)鎖，閥門機械鎖裝置，防止人為誤操作。閥門機械鎖是安裝與閥門上的鎖定裝置，可以將兩個或多個閥門鎖定后，遵循規(guī)定的操作順序進行安全有序的操作，防止誤操作導致事故的發(fā)生。

凱研機械公司提供多種類型的閥門機械聯(lián)鎖，適用于各種類型的閥門，如：球閥、蝶閥、閘閥、截止閥、電動閥、盲板閥及管道收發(fā)球系統(tǒng)。

閥門機械鎖裝置特點

1、每臺閥門的裝置上配備兩把不同的帶有編碼的鑰匙，控制閥門的兩種狀態(tài)。

2、裝置上留存兩把鑰匙的條件下，閥門處于可操作狀態(tài)，通過操作實現(xiàn)鑰匙的轉(zhuǎn)換。

3、裝置上留存一把鑰匙的條件下，閥門處于鎖定狀態(tài)，鑰匙的位置標識閥門的狀態(tài)。

4、通過“鑰匙傳遞”，實現(xiàn)閥門信息的遠程傳遞和狀態(tài)顯示。

5、結構緊湊堅固，操作靈活簡便。 

6、采用不銹鋼材質(zhì)，產(chǎn)品壽命長久。

7、安裝簡便，不改變受控閥門的性能和形狀，適合于多種類型的閥門。

2、閥門機械鎖裝置工作原理

初始狀態(tài)

 裝置對應的孔位上留存一把鑰匙，受控閥門處于初始狀態(tài)（開或關）

操作狀態(tài)

根據(jù)工藝要求，從控制室取出授權鑰匙，插入裝置上另一側(cè)對應的孔位，受控閥門處于可操作狀態(tài)，操作閥門至新的狀態(tài)（開或關）

結束狀態(tài)

拔出初始狀態(tài)中留存的鑰匙，并返回控制室，受控閥門鎖定于重新設定的狀態(tài)（開或關）。

3、應用范圍

閥門機械聯(lián)鎖主要應用于 油田、石化、化工、核電、冶金、天然氣等高危行業(yè)中關鍵閥門的狀態(tài)鎖定、傳遞和顯示（現(xiàn)場和控制室）。

n theactual operation process, it is called ”mechanical interlocking"that the key is exchanged in a certain logical order to realize thesafe operation process. It is a kind of mechanical device approvedby the world safety organization and standard organization, whichcan prevent man-made misoperation. 

Thepurposeof installing mechanical interlocking is to ensure thatthee and its auxiliary e can operate in accordancewith the process set. In order to eliminate the iueparableconse caused by human error operation. 

Inpetroleum, chemical, powe r and high-risk manufacturing industries,there are a large number of manual operation e, electricale, protective safety doors and so on. Accidents caused bymisoperation are co1mnon, and serious casualties and economiclosses caused by misoperation also occur from time to time.Statistics show that 70% of accidents in the oil and gas industryare caused by human errors. The rapid development of modernindustry has further aggravated the risk factors, which arecontrolled by personnel. However, human beings themselves will be disturbed by extemal factors, such asstress, disease andother factors -all in all, depending on ”humanfactors”． 

Valvesafety mechanical interlock 

In manyindustrial processes, valves play a very important role in safety.A misoperation of a valve can lead to a series of dramatic andserious conse - personal injury, factmy damage, and evenirTeparable environmental pollution. Therefore, the valve safetyoperation must be effectively monitored. Through the use of Kaiyanvalve mechanical interlocking can ensure that always in accordancewith the correct order of operation.

Kaiyanvalve mechanical interlocking device can be installed in eachhandle or handwheel operated valve, without adjusting, altering ordestroying the original valve e. The intedocking device isve1y strong and easy to operate and clearly display the switchingstatus of each valve．

Professionallydesigned customized keys and interlocks make assembly without anyadjustment or processing. We will provide a full set ofinterlocking system and installation and commissioning services, sothat you have no worries. Provide a set of special tools foron-site emergency adjustment o「 expansionof on-site safety system. Unique designed dust-p「oofsealing cover prevents dust or sediment from entering thekeyhole.
